Patient with alveolar abscess due to dental caries with severe alveolar bone loss,
severe tooth mobility, root resorption need extraction of tooth because it is impossible to
carry out pulp treatment and restoration by using conventional method. Early loss of
primary molar might cause masticatory interference, extrusion of opposing tooth, problem
in maintaining space and interference on eruption of permanent tooth. Especially, early
loss of primary second molar before the eruption of permanent first molar might cause
space closure by mesially erupted permanent first molar and impaction of second
premolar. In such a case, distal shoe space maintainer and removable space regaining
appliance was the first choice of treatment. But, distal shoe space maintainer need
precise adaptation and might cause chronic inflammation if the oral hygiene is poor. In a
case using removable space regaining appliance, patient's cooperation is most important.
If the distal root of primary second molar is comparably sound and alveolar abscess
with alveolar bone loss is localized at mesial root, hemisection should be carried out for
precise guide to eruption of the permanent first molar, restoration of masticatory fuction
and solution to the discomfort of the patient.
